1 Claim.

This invention relates generally to shingles and particularly to aluminum shingles as set forth in detail in my co-pending application, Serial No. 776,332, filed September 26, 1947, over which the shingle shown herein is an improvement.

The main object of this invention is to devise a metal shingle of the interlocking type in which provision is made to prevent leakage from heavy run-off, on condensation, or both.

I accomplishthis and other objects in the manner set forth in the following specification as illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of the shingle from the innerside.

Fig. 2 is a perspective view of the shingle from the weather side.

Fig. 3 is a fragmentary perspective view of one corner of the shingle showing the drain slot which forms the basis of this invention.

Fig. 4 is a fragmentary vertical section through an overlapping joint showing the purpose of the drain.

Fig. 5 is a fragmentary section along the line 55 in Fig. 4 through the butt end of the shingle and passing through the drain slot.

Fig. 6 is a section taken along the line 66 in Fig. 4.

Like numbers of reference refer to the same or similar parts throughout the several views.

Referring in detail to the drawing there is shown a rectangular metal metal shingle consisting of a plurality of panels l preferably grained by score marks II impressed into the metal in simulation of wood and divided by the grooves l2 which provide run-01f gutters as well as a footing for the shingle, as shown clearly in Fig. 6.

The front of the shingle has a lateral outturned edge l3 and horizontal upper edge Id which is also outturned. A nailing tab I extends from the junction of the edges l3 and M.

On the rear or inner sides of the shingle is an inturned gutter edge It and an inturned lateral edge I! which is normal to the edge IS.

The edges I3 and H are what is commonly known as fiat seams, as shown in Fig. 3.

The edges [4 and iii are reversely curved and the material in the shingle is resilient enough to insure a close fit at the point of tangency l8 between the tip l9 and the butt 2!) of the next shingle above.

While this seal has certain advantages, it also acts as a trap in which rain water and condensation can collect and finally form a leak. To overcome this possibility, I have provided each gutter edge l6 With a drain slot 2| near the corner 2 22 of the shingle. Obviously more slots 2| may be employed without departing from the spirit of this invention. To provide for reinforcement and stiffening of the shingle, the same is provided with laterally spaced fiat sections l2 which extend from the top to the bottom edge of the shingle, and ribs l I which extend generally parallel with the flat sections and which are substantially coextensive therebetween, as illustrated in Figures 2 and 3.

Any moisture collecting in the gutter formed by the edge It will drain out upon the weather side of the next lower shingle. The purpose in having the drain slot 2| near the corner 22 is to keep it as far as possible from the joints in the next lower course.

The lateral edges of the shingle are reversely turned on opposite faces of the shingle providing curved outer edge portions for interlocking the shingle with laterally adjacent shingles. The top and bottom edge portions are reversely turned, as illustrated in Figures 1 and 2, each comprising a half-round portion, as illustrated at l9 and 20 of Figure 4. The reversely curved bottom edge portion of a shingle is adapted to engage with a reversely curved top edge portion of a lower adjacent shingle to form a close fit therebetween. The corrugation ridges on the inner face of a shingle, as shown in Figure 5, are adapted to space the reversely turned top edge portion of a lower adjacent shingle from the inner face of the shingle so that moisture can travel along the inner face and into the gutter.

I claim:

An aluminum shingle of rectangular shape, said shingle comprising a substantially flat sheet of metal of uniform thickness and the body of which lies substantially in the same plane, corrugations in said shingle spaced laterally of the shingle, said corrugations forming ridges on the inner face of the shingle, the lateral edges of the shingle being reversely turned on opposite faces of said shingle providing curved outer edge portions for interlocking the shingle with laterally adjacent shingles, the top and bottom edge portions of the shingle being reversely turned on opposite faces thereof, each of said top and bottom turned edge portions comprising a halfround portion, one side of which is tangent to the plane of the shingle and the other side of which terminates in a reversely curved portion, the turned bottom portion forming a gutter and the reversely curved portion thereof being engageable with a reversely curved top edge portion of a lower adjacent shingle to form a close fit therebetween, a, fastening tab integral with the shingle and extending from an upper corner of said shingle for securing the same to a roof structure, and a drain slot disposed in the gutter of said shingle for draining water therefrom, said 5 corrugation ridges on the inner face of the shingle adapted to space said reversely turned top edge portion of the lower adjacent shingle from the inner face of said shingle so that moisture can travel along the inner face of the shingle and 10 into said gutter.
